The U.N. Security Council can pass resolutions which all U.N. member states are required to comply with. 5 of these are permanent members. The permanent members can veto any action of the Security Council.
In 1950 the Security Council passed SC Resolution 83, which sanctioned the use of combined forces to repel the North Korean invasion of South Korea. The action passed - partially because the Soviet Union was boycotting the United Nations at the time.
I am wondering what could have happened if the Soviet Union had vetoed this resolution. Did the UN's policies in 1950* contain a way to pass a resolution if one of the permanent members vetoes it? Could the UN have intervened another way if the Soviet Union had vetoed this resolution?
Shortly after this the U.N. passed Resolution 377, which allows the General Assembly to act when the 5 permanent members of the Security Council don't agree. This question is about what tools were available prior to Resolution 377
